Abstract
This study proposes a method using mean comparison to improve the accuracy of interferometry processing correlation time delay under the low signal-to-noise ratio and low residual time delay. The method uses the means of taking the average of stripe subsection, comparing threshold and eliminating outliers, which offsets the influence of channel noise on the accuracy of the signal. Using the direct method under the same SNR strike delay simulation comparison proved that the mean comparison method can get relatively high accuracy of time delay information.
